In the final part of this series, David Scott asks whether MPFR and FPP-Reg-FCAS Recovery have delivered on their goals, then uses the data to explore how AEMO might procure Regulation FCAS more dynamically and tune AGC to make better use of it.

In part three of this series, David Scott examines the first year of FPP-Reg-FCAS Recovery settlements, revealing which technologies paid and which were paid, and showing how semi-scheduled wind and solar farms, scheduled generators and batteries have each responded to the new incentives.

In part two of this series, David Scott dives into AEMO's 4-second FPP data to show how dispatch errors are classified as good or bad, how Regulation FCAS usage is measured, and how these calculations translate into FPP payments and Reg-FCAS Recovery charges.
